Diagnosing Relay Selection on Linux Endpoints

Usage and Config Platform
1

Wanted to know if anyone had any pointers on diagnosing relay autoselection issues for Linux endpoints. On the windows side you can run the client diagnostics with the -r option to run relay selection to log how the client runs through the relay list but I cannot find a similar command on the linux side.

Here is an example log retrieved from an endpoint where we forced a relay selection: (note the XXX which is masked data)

The key logging for troubleshooting this will be client debug logging

Activate client debug logging, get the client to go through its relay selection cycle and let’s look at the results.

You’ll see a series of rounds of ICMP pings (or not) to which you can see all the relays the client knows about in its Relays.dat file in the actionsite having ICMP pings sent to them. And the results of the ICMP conversation to determine which relay the client selected.
